You have 6 PV panels that each have the same I-V curve (ISC = 5.5 A, VOC = 45 V).  (a) How many connection configurations that use all 6 panels are possible? Draw  each one.  (b) Draw the I-V curves for each of the configurations on one graph. You may draw  the curves by hand or use a software of your choice. Clearly label each curve.  (c) Assume you are to power a 2.5 Ω load with the panels. Knowing that dimmer  sunlight reduces the current output of the cells but not the output voltage, what  configuration would be best if you were to build it? Explain your answer.

Electrical Heating Unit

The conversion of electrical energy to heat energy is known as electric heating. The heating system that converts the electrical energy to heat energy for various application is called electrical heating unit. Electricity is employed as the firing mechanism in electric heating systems, which transforms electric current to heat. Electric heaters have heating elements in the form of electric resistors.
